Cameo? Prooflike? The camera doesn't lie!
Over the years I've accumulated some CAC coins that appear to be Cameo or Prooflike. They have mirror surfaces. Finally, I got up the courage to submit them to CACG and asked whether the other two grading services had missed the designations. Well, here are the results. The first picture shows what a true Cameo should look like.
Not Cameo - notice the dark fields are not consistent
Not Prooflike - there is no dark field!
